Our company is a respected manufacturer, supplier and exporter of a massive range of Flush Doors. These are ready to use doors which can be easily placed with minimal endeavor. To manufacture these doors, we use chosen and well seasoned imported pine wood timber that are tested by permanent preservatives. The core of the doors is framed with seasoned wood and is made it robust by a layer of cross bands. It makes the Flush Doors resistance against borer, termite and dimensionally stable in natural cyclic changes.
Both side lock rails are provided for sufficient strength to the handles and knobs.
All core, battens and frames are treated with special chemical, which makes the door stable in case of borer and termite attack.
BWP grade PF resin is used during manufacturing which provide long life to doors in any climate.
| Applications | : | Pragati flush doors are widely used for residential and commercial complexes, schools, restaurants, hotels, offices, cinema halls, apartments etc. |
